Question

A force of 1800 N acts on the surface of a rectangular block of length 6m and breadth
4m. What is the pressure exerted by this box?

Answer 1

Explanation:

length of block = 6m

breadth of block = 4m

area of block = l*b

area of block = 24sq m

force applied on block = 1800 N

pressure exerted by block = force /area

1800/24 = 75pascal

Answer 2

the pressure that is exerted by the rectangular block is equal to 75 Pascal or Newton per  metre square

Explanation:

• The pressure exerted by a surface can be defined as the force applied per unit area.

• the force that has been applied on the block is given as 1800 N

• The length of the block is equal to 6 metre and the breadth of the block is equal to 4m.

• Therefore the area of the block is equal to 24 square metre since the area is the product of length and breadth.

• Therefore the pressure is the force per unit area which is equal to, 1800/24Pa = 75 Pa
